FreeBSD : GnuTLS -- improper SSL certificate verification (856a6f84-8b30-11de-8062-00e0815b8da8)

high Nessus Plugin ID 40659
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

GnuTLS reports :

By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS into 1) not printing the entire CN/SAN field value when printing a certificate and 2) cause incorrect positive matches when matching a hostname against a certificate.

Solution

Update the affected packages.
